Optionally record the special files (symlinks, fifos, sockets, character
and block devices) using reparse points instead of using Interix representation.
Doing so, the special files are interoperable with Windows Subsystem for
linux (WSL).
Windows traditionally rejected having both EA and reparse data assigned
to a file, but Windows 10 has dropped the constraint and it uses this
condition massively, so do the same. Note that pre-Windows 10 chkdsk.exe
removes the EA' on reparse points, potentially damaging more recent
volumes.
The Windows Subsystem for Linux (WSL) of Windows 10 uses reparse points
to record special files (symlinks, fifos, sockets, char or block devices).
Honor such reparse points with the same meaning as WSL.
A number of functions in libntfs-3g are generally useful, but are tied to
extended attributes support and are not included when the library is
built on platforms without extended attributes support.
This proposal updates libntfs-3g to always include these functions.
The only tricky part is dealing with the XATTR_CREATE and XATTR_REPLACE
flags. These flags are defined in <sys/xattr.h>, so they must be
redefined on platforms without extended attributes support.
